...SECTION A 1. What are the capabilities of the XO laptop (especially the latest version, XO-3)? How well-suited is this machine for developing countries? The One laptop per child organization (herein referred to as OLPC) was started by MIT’s Nicholas Negroponte in 2005. And the mission statement of the organisation is as follows: “To create educational opportunities for the world's poorest children by providing each child with a rugged, low-cost, low-power, connected laptop with content and software designed for collaborative, joyful, self-empowered learning. When children have access to this type of tool they get engaged in their own education. They learn, share, create, and collaborate. They become connected to each other, to the world and to a brighter future” Their aim was to provide this laptop at a cost of $100 and Mary Lou Jepson, as chief technical officer of OLPC had to consider a range of environmental factors for the design to be tailored to the particular needs of the developing world (Buchele, 2009:1). These challenges included electricity availability, extreme temperatures and the rugged physical environments of these countries (Brown, 2009:8). After several years of research and development, the result was the XO laptop featuring hardware innovation in power supply, display, durability and networking. The first model XO1 was launched in November 2007 at a cost of $188, failing at the initial goal price of $100 but it revolutionized the PC industry to be motivated...

What we do is we sell one Guide billions and billions of times. We exploit the multidimensional nature of the Universe to cut down on manufacturing costs. And we don’t sell to penniless hitchhikers. What a stupid notion that was! Find the one section of the market that, more or less by definition, doesn’t have any money, and try to sell to it. No. We sell to the affluent business traveler and his vacationing wife in a billion, billion different futures. This is the most radical, dynamic and thrusting business venture in the entire multidimensional infinity of space-time-probability ever.” ... Ford was completely at a loss for what to do next. “Look,” he said in a stern voice. But he wasn’t certain how far saying things like “Look” in a stern voice was necessarily going to get him, and time was not on his side. What the hell, he thought, you’re only young once, and threw himself out of the window. That would at least keep the element of surprise on his side. ... In a spirit of scientific inquiry he hurled himself out of the window again. Douglas Adams Mostly Harmless Strangely, the thing that least intrigued me was how they’d managed to get it all done.
